在 wrist之dorsal side有6個 extensor compartment
Compartment 1(位於radial bone的側面): Extensor pollicis brevis、Abductor pollicis longus(靠radial side) 
Compartment 2(位於radial bone的dorsal side): Extensor carpi radialis brevis、Extensor carpi radialis longus
(註）Compartment 2與Compartment 3中間有Lister's tubercle
Compartment 3(位於radial bone的dorsal side): Extensor pollicis longus(在Lister's tubercle呈45度轉折)
(註）Compartment 1與Compartment 3是構成snuff box的重要borders
Compartment 4(位於radial bone的dorsal side): Extensor digitorum and extensor indicis
Compartment 5(位於ulnar bone的dorsal side): Extensor digiti minimi
Compartment 6(位於ulnar bone的側面): Extensor carpi ulnaris 
這些tendon位於 wrist之dorsal side與palmar side之flexor tendon比較
其tendon之mpophology較扁平而flexor tendon較圓實
所以一般整型外科醫師都可對手術完之flexor tendon作拉扯而extensor tendon則儘量減少tension
而兩側tendons之相同處則是都有shealth (tenosynovium)
一般來說
extensor tendon之受傷機轉與repetitve strain有關 (overuse)
而受傷後通常是tenosynovitis
最著名的例子則是Compartment 1之De Quervain's syndrom
治療上是以DFM為主並將tendon擺在最大容忍之stretch position
之後可配合T-taping來unloading或splinting
No exercise is necessary.
